School nurses focus on students' overall health. They may work in one school or in several, visiting each for a part of the day or week. They may also assist the school physician, if the school employs one. They work with parents, teachers, and other school and professional personnel to meet student's health needs. School nurses promote health and safety, work to prevent illnesses, treat accidents and minor injuries, maintain students' health records, and refer students who may need additional medical attention. School nurses may also oversee health education programs and school health plans. They also administer medication to children and see that special needs students' health requirements are met. School nurses are employed at the elementary, middle, and high school levels. There are nearly 74,000 registered nurses working as school nurses, according to the Health Resources and Services Administration.
